Hello everyone! I bought a used Tomtom GO Basic 6-inch device! I wanted to update it, but MDC didn't recognize it with any of the original cables.
Just a warning to others. TomTom's entire recent generation of devices has always had a flaw in the code that prevents these devices from making a proper USB connection to any computer. As a result, none of them work with MyDrive Connect which depends upon that connection.
By 'recent' generation, I mean most of what's been sold in the last year or so, including
anything starting with serial number characters YA, YB, YC, ZU, ZV, ZW, B3, B4, B7.
This bug has been on TomTom's radar for more than a year now.
The good news is that the only real advantage to connecting any of these devices to MyDrive Connect (or basically, connecting to your computer at all) is to add a new voice, so the hit isn't too awful in actual practice. Everything else can be updated over WiFi. This still doesn't excuse TomTom for not having this bug, a very basic USB function, remedied before these devices were released to the public.
That said, the OP's device is older than the series mentioned above (his will have a serial starting with X5, X6, X7 or X8), and should connect correctly to USB for use with MyDrive Connect.
